Title: Desinfection de composants du sang, de tissus corneens et sclerotiques
Inventor: RUBINSTEIN ALAN I
IPC: A61P7/08
Filed: 1989-08-08
Abstract: Un procédé de désinfection de certains composants du sang, notamment des globules rouges, des plaquettes et des proteines, et de tissus cornéens et sclérotiques, rend ces composants inoffensifs et propres à la transfusion ou à la transplantation chez des êtres humains, tout en leur conservant leurs fonctions biologiques ou optiques. On prépare une solution de stérilisation avec par exemple un désinfectant disponible dans le commerce (tel que LDR de la compagnie Alcide) et contenant surtout de l'acide lactique et du chlorate de sodium. On utilise comme diluant une solution saline normale en place d'eau distillée. On expose les composants du sang ou les tissus cornéens ou sclérotiques au désinfectant pendant une durée suffisante pour désactiver ou réduire la capacité d'infection d'agents pathologiques. L'environnement salin normal évite ou empêche l'hémolyse des globules rouges du sang, de l'épithélium ou de l'endothélium cornéens ou sclérotiques, la rupture des plaquettes ou la dénaturation des protéines.

Title: Polymer-supported 4-(n-benzyl-n-methylamino)pyridine catalyst and process for same.
Inventor: MCQUIGG DONALD WAYNE
IPC: C08F26/06
Filed: 1989-09-21
Abstract: A cross-linked polymer-supported 4-(N-benzyl-N-methylamino) pyridine material and process for its preparation in high yield and having effective physical and catalytic properties. The polymer-supported catalyst is characterizd by the suspension copolymerization of an organic phase containing the corresponding vinyl-substituted pyridine monomer, a styrene monomer, and a suitable cross-linking agent and free radical-generating catalyst in the presence of an aqueous phase containing a cellulose ether derivative as the stabilizing agent. The catalyst is further characterized by its yield in excess of 90% by weight and by its predominant and generally spherical and smooth bead form and substantially uniform size that is efficiently hard and durable and possesses sufficient catalytic activity for effective use in acylation, alkylation or other related reactions.

Abstract: Ce procédé de traitement de données protégées par chiffrement est particulièrement bien adapté pour être appliqué aux cartes à microcircuit utilisant le système DES. Ledit procédé permet de traiter la permutation irrégulière de la clé à partir d'une table de correspondance, opération qui est la plus coûteuse en temps de traitement et en taille de code dans ce système. Ainsi le procédé consiste à décomposer la permutation initiale en une pluralité de permutations élémentaires de telle sorte que le plus grand nombre d'entre elles soit opéré sur au moins deux éléments binaires, les éléments binaires des différents octets de la clé étant repérés, et un système de masquage étant appliqué afin d'extraire les éléments binaires adéquats pour les permuter aux emplacements prédéterminés par la table de correspondance.

Abstract: A method for positioning excitation pulses for a linear predictive coder (LPC) operating according to the multi-pulse principle, i.e. a number of such pulses are positioned at specific time points and with specific amplitude. The time points and the amplitudes are determined from the predictive parameters (a k ) and the predictive residue signal (d k ), by correlation between a speech representa­tive signal (y) and a composed synthesized signal (ŷ). This can provide all possible time positions for the excitation pulses within a given frame interval. According to the proposed method, the possible time positions are divided into a number (n f ) of phase positions and each phase- position is divided into a number of phases (f). These phases are vacant for the first excitation pulse. When this pulse has been positioned, the phase determined for this pulse is denied to the following excitation pulses until all pulses in a frame have been positioned.

Abstract: An apparatus for discriminating acceptable products from rejectable products for injection molding machines, capable of carrying out this discrimination accurately and automatically without using a sample of an acceptable product. While a molding cycle for the mass production of molded products is carried out in accordance with the optimum molding conditions in a mold file which is read out from a shared memory (105), an actual resin pressure detected by a pressure sensor (4) is sampled periodically in accordance with an output from an address generator (118). In the meantime, a reference resin pressure sampled at the corresponding sampling cycle on the same or a pressure varying pattern, in an acceptable product molding process for the determination of optimum molding conditions which has been carried out before the mass production of the products, is read out of the shared memory (105) by a processor (114). The actual resin pressure is compared with the reference resin pressure, and, when the absolute value of the difference therebetween is outside an allowable range, the value on rejectable sample counter is incremented. When the value, which is representative of the frequence of occurrence of improper actual resin pressure before the termination of a dwelling operation, on the counter at the time of termination of the dwelling operation is not higher than an allowable level, an acceptable product signal is sent out, while when the value on the counter exceeds the allowable level, a rejectable product signal is sent out.

Title: FACTOR Xa BASED ANTICOAGULANT COMPOSITIONS.
Inventor: ESMON CHARLES T
IPC: A61K38/48
Filed: 1990-06-06
Abstract: An anticoagulant composition containing an effective amount of factor Xa having the active serine site inactivated that functions rapidly and effectively in vivo to suppress coagulation. In a preferred embodiment, Factor Xa, a serine esterase that forms a complex with Factor Va, Ca++, and phospholipid to catalyze prothrombin activation, is first inactivated with an active site inhibitor, such as dansyl-glu- gly-arg-chloromethyl ketone, to form inactivated factor Xa. In another embodiment, Factor Xa is expressed from a gene sequence wherein the portion encoding the active serine region is modified. The inactivated protein retains the ability to bind to endogenous factor Va in vivo, and has a half-life of approximately ten hours. Administration of inactive factor Xa to the blood of a patient results in the formation of inactive factor Xa-Va complexes in vivo, thereby inhibiting coagulation.
